In current implementation, passive cooling is always enabled. But, I
believe that _PSV has higher value than _ACx in usual. Thus, when AC
is online, active cooling is preferred.
My understanding is that passive cooling became active with AC online,
then became AC offline during passive cooling is active in his case.
I cannot understand why passive cooling is active so aggressively even
when AC online. I suspect that his laptop doesn't have any fan, or
his fan couldn't be active due to some reason.
Sincerely,
